Lysosomal Activation Mediated by Endocytosis in J774 Cell Culture Treated with N-Trimethyl Chitosan Nanoparticles. Molecules 2024; 29:3621. [PMID: 39125026 PMCID: PMC11313802 DOI: 10.3390/molecules29153621] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2024] [Revised: 07/22/2024] [Accepted: 07/29/2024] [Indexed: 08/12/2024] Open
Abstract
Safety and effectiveness are the cornerstone objectives of nanomedicine in developing nanotherapies. It is crucial to understand the biological interactions between nanoparticles and immune cells. This study focuses on the manufacture by the microfluidic technique of N-trimethyl chitosan/protein nanocarriers and their interaction with J774 cells to elucidate the cellular processes involved in absorption and their impact on the immune system, mainly through endocytosis, activation of lysosomes and intracellular degradation. TEM of the manufactured nanoparticles showed spherical morphology with an average diameter ranging from 36 ± 16 nm to 179 ± 92 nm, depending on the concentration of the cargo protein (0, 12, 55 μg/mL). FTIR showed the crosslinking between N-trimethyl chitosan and the sodium tripolyphosphate and the α-helix binding loss of BSA. TGA revealed an increase in the thermal stability of N-trimethyl chitosan/protein nanoparticles compared with the powder. The encapsulation of the cargo protein used was demonstrated using XPS. Their potential to improve cell permeability and use as nanocarriers in future vaccine formulations was demonstrated. The toxicity of the nanoparticles in HaCaT and J774 cells was studied, as well as the importance of evaluating the differentiation status of J774 cells. Thus, possible endocytosis pathways and their impact on the immune response were discussed. This allowed us to conclude that N-trimethyl chitosan nanoparticles show potential as carriers for the immune system. Still, more studies are required to understand their effectiveness and possible use in therapies.

Abstract
Cancer phototherapy has been introduced as a new potential modality for tumor suppression. However, the efficacy of phototherapy has been limited due to a lack of targeted delivery of photosensitizers. Therefore, the application of biocompatible and multifunctional nanoparticles in phototherapy is appreciated. Chitosan (CS) as a cationic polymer and hyaluronic acid (HA) as a CD44-targeting agent are two widely utilized polymers in nanoparticle synthesis and functionalization. The current review focuses on the application of HA and CS nanostructures in cancer phototherapy. These nanocarriers can be used in phototherapy to induce hyperthermia and singlet oxygen generation for tumor ablation. CS and HA can be used for the synthesis of nanostructures, or they can functionalize other kinds of nanostructures used for phototherapy, such as gold nanorods. The HA and CS nanostructures can combine chemotherapy or immunotherapy with phototherapy to augment tumor suppression. Moreover, the CS nanostructures can be functionalized with HA for specific cancer phototherapy. The CS and HA nanostructures promote the cellular uptake of genes and photosensitizers to facilitate gene therapy and phototherapy. Such nanostructures specifically stimulate phototherapy at the tumor site, with particle toxic impacts on normal cells. Moreover, CS and HA nanostructures demonstrate high biocompatibility for further clinical applications.

Abstract
Quaternary Trimethyl Chitosan (QTMC) and QTMC-Silver Nanoparticles (QTMC-AgNPs) have been synthesized, characterized, and tested as antibacterial agents against Staphylococcus aureus, Escherichia coli, and two plant fungi (Sclerotium rolfsil and Fusarium oxysporum). The as-prepared water-soluble QTMC was in situ reacted with silver nitrate in the presence of clean compressed hydrogen gas (3 bar) as a reducing agent to produce QTMC-AgNPs. UV-vis, ATR-FTIR, HR-TEM/SEM, XPS, DLS, XRD, and TGA/DTG were employed to assess the optical response, morphology/size, surface chemistry, particle size distribution, crystal nature, and thermal stability of the synthesized QTMC-AgNPs, respectively. The as-prepared QTMC-AgNPs were quasi-spherical in shape with an average particle size of 12.5 nm, as determined by ImageJ software utilizing HR-TEM images and further validated by DLS analysis. The development of crystalline nanoparticles was confirmed by the presence of distinct and consistent lattice fringes with an approximate interplanar d-spacing of 2.04 nm in QTMC-AgNPs. The QTMC-AgNPs exhibited significant antibacterial activity with a clear zone of inhibition of 30 mm and 26 mm around the disks against E. coli and S. aureus, respectively. In addition, QTMC-AgNPs showed highly efficient antifungal activity with 100% and 76.67% growth inhibition against two plant pathogens, S. rolfsii and F. oxysporum, respectively, whereas QTMC revealed no impact. Overall, QTMC-AgNPs showed a promising therapeutic potential and,thus, can be considered for drug design rationale.

Abstract
Diabetes mellitus greatly affects the quality of life of patients and has a worldwide prevalence. Insulin is the most commonly used drug to treat diabetic patients and is usually administered through the subcutaneous route. However, this route of administration is ineffective due to the low concentration of insulin at the site of action. This route of administration causes discomfort to the patient and increases the risk of infection due to skin barrier disturbance caused by the needle. The oral administration of insulin has been proposed to surpass the disadvantages of subcutaneous administration. In this review, we give an overview of the strategies to deliver insulin by the oral route, from insulin conjugation to encapsulation into nanoparticles. These strategies are still under development to attain efficacy and effectiveness that are expected to be achieved in the near future.

Abstract
Chitosan, as a biodegradable and biocompatible polymer, is characterized by anti-microbial and anti-cancer properties. It lately has received a widespread interest for use as the pulmonary particulate backbone materials of drug carrier for the treatment of infectious disease and cancer. The success of chitosan as pulmonary particulate drug carrier is a critical interplay of their mucoadhesive, permeation enhancement and site/cell-specific attributes. In the case of nanocarriers, various microencapsulation and micro-nano blending systems have been devised to equip them with an appropriate aerodynamic character to enable efficient pulmonary aerosolization and inhalation. The late COVID-19 infection is met with acute respiratory distress syndrome and cancer. Chitosan and its derivatives are found useful in combating HCoV and cancer as a function of their molecular weight, substituent type and its degree of substitution. The interest in chitosan is expected to rise in the next decade from the perspectives of drug delivery in combination with its therapeutic performance.

Abstract
Anaplastic lymphoma kinase (ALK) is a major target in treating non-small-cell lung cancer, and several ALK inhibitors have been developed to antagonize its kinase activity. However, patients treated with inhibitors ultimately develop drug resistance. Therefore, therapies with new mechanisms of action are needed. Proteolysis targeting chimeras (PROTACs) are molecules that comprise a ligand for binding a protein of interest (POI), a connecting linker and a ligand for recruiting E3 ligase, and cause degradation of the target POI. Here, the first multi-headed PROTAC, as a proof of concept, is developed as a gold nanoparticle (GNP)-based drug delivery system for delivering PROTACs to target ALK. Pegylated GNPs loaded with both ceritinib and pomalidomide molecules, termed Cer/Pom-PEG@GNPs, showed good stability in several media. The GNP conjugates potently decreased the levels of ALK fusion proteins in a dose- and time-dependent manner, and specifically inhibited the proliferation of NCI-H2228 cells. In comparison with small molecule PROTACs, the new multi-headed PROTAC promoted the formation of coacervates of POIs/multi-headed PROTAC/E3 ubiquitin ligases, and POI and E3 ubiquitin ligase interacted through multidirectional ligands and a flexible linker, thereby avoiding the need for complicated structure optimization of PROTACs. In conclusion, Cer/Pom-PEG@GNPs can degrade intracellular ALK fusion proteins with minor off-target toxicity and can be applied in patients resistant to ALK inhibitors. As a nano-based drug carrier, Cer/Pom-PEG@GNPs have the potential to enable prolonged circulation and specifically distribute drugs to tumor regions in vivo; thus, further investigation is warranted.

Abstract
Intraorgan targeting of chemical drugs at tumor tissues is essential in the treatment of solid tumors that express the same target receptor as normal tissues. Here, asialoglycoprotein receptor (ASGP-R)-targeting paclitaxel-conjugated gold nanoparticles (Gal/PTX-GNPs) are fabricated as a demonstration to realize the precise treatment of liver cancer. The enhanced biological specificity and therapeutic performance of drugs loaded on nanoparticles not only rely on the ligands on carriers for receptor recognition but are also determined by the performance of gold conjugates with designed structure. The tumor cell selectivity of the designed conjugates in liver tumor (HepG2) cells is close to six times of that incubated with control conjugates without galactose modification in liver normal (L02) cells. The drug level in tumor versus liver of Gal/PTX-GNPs is 121.0% at 8 h post injection, a 15.7-fold increase in the tumor specificity compared to that of GNPs conjugated with PTX only. This intraorgan-targeting strategy results in a considerable improvement of performance in treating both Heps heterotopic and orthotopic xenograft tumor models, which is expected to be used for the enhanced antitumor efficacy and reduced hepatotoxicity in liver cancer treatment.

Abstract
Drug-conjugated gold nanoparticles (GNPs), which are generally constructed with many molecules of thiol-terminated polyethylene glycol (PEG)-drug decorated on their surfaces via a thiol-Au covalent bond, are promising and efficient nanoprodrugs. However, because of the exposure of the hydrophobic drug molecules on the surface of the conjugate, in vivo stability, opsonization, and subsequent inefficient therapy become the main issues of this system. To solve these problems without complicating the structures of gold conjugates, herein we propose a method to change the relative position of PEG and the drug. A novel gold conjugate (GNP-NHN═Dox-mPEG) with doxorubicin (Dox) shielded by PEGylation on the surface of GNPs is designed. It demonstrates improved solubility, stability, and dispersion and achieves a two-step stimulus-responsive drug release in response to an acidic environment in lysosomes and then esterase in the cytoplasm. This unique manner of release enables the cytoplasm to act as a reservoir for sustained drug delivery into the nucleus to improve antitumor efficacy in vivo. The intratumoral drug concentrations of the conjugate reach 14.4 ± 1.4 μg/g at 8 h, a two-fold increase in the drug concentration compared with that of the doxorubicin hydrochloride group. This molecular design and regulation approach is facile but important in modulating the in vivo performance of nanovehicles and demonstrates its vital potential in developing effective nanoparticle-based drug delivery agents.

Abstract
The pH-sensitive gold nano hydrogel based on itaconic acid, acrylic acid and triethylene glycol (GIAT) has been prepared by free radical polymerization viz. organic solventless approach with different monomer ratios. The nature of bonding and structural identification of GIAT hydrogels were characterized by FT-IR spectroscopy. The surface morphology of gold gel was examined using scanning electron microscopy (SEM). In addition, transmission electron microscopy (TEM) was used to identify the size of gold nano particles. The in vitro biocompatibility of GIAT hydrogel has been evaluated in 3T3 fibroblast cell lines. The obtained results show that gold nano particle incorporated hydrogel possess ~99% of cell proliferation. Followed by, the impact of gold nano particles on swelling, surface morphology was studied. The consecutive preparation of hydrogel, effect of different pH conditions, and stoichiometry of monomeric units have also been discussed. The degree of swelling was measured in carbonate buffer solutions for 24h period with varying pH such as 1.2, 6.0, 7.4 and 10.0. The obtained results showed that the stoichiometry of itaconic acid and gold nano particles plays an essential role in modifying the nature of GIAT polymeric hydrogels. In conclusion, promising Au-nano incorporated pH-sensitive bio polymeric hydrogels were prepared and characterized. The unique properties of these Au-nano hydrogel make them attractive use in biomedical applications.

Abstract
Although combination delivery (co-delivery) shows much superiority in the defect compensation of single-agent therapy, the construction and application of co-delivery systems are still challenging, especially for protein-based joint systems. In this work, a series of chitosan (CS)-amino acid derivatives (Arg-CS, Lys-CS, and Phe-CS) with different degrees of substitution (DS) were synthesized to prepare CS nanocapsules (CNCs) using a simple emulsification method in the presence of linoleic acid (LA). The hydrophobic drug can be loaded in LA droplets, and a positively charged protein stabilized the optimized Arg-CS nanocapsules (Arg-CNCs) on their negative surfaces. The in vitro antitumor efficacy of Arg-CNCs co-delivering paclitaxel and recombinant human caspase-3 was evaluated in HeLa cells. The co-delivery system displayed much lower IC50 values and a higher percentage of apoptotic cells compared with the control groups. This system provides a promising and universal strategy for co-delivery, leading to collaborative tumor treatment.

Mechanism of surface charge triggered intestinal epithelial tight junction opening upon chitosan nanoparticles for insulin oral delivery. Carbohydr Polym 2016; 157:596-602.

Abstract
Intestinal epithelium is a major barrier limiting the absorption of oral insulin owing to the presence of intercellular tight junctions (TJs). Previous studies proved that carboxymethyl chitosan/chitosan-nanoparticles (CMCS/CS-NPs) exhibited surface charge depending promotion of intestinal absorption. This study further confirmed the better performances of insulin:CMCS/CS-NPs(-) in enhancing epithelial permeation, increasing bioavailability and extending blood duration of insulin than insulin:CMCS/CS-NPs(+). Immunohistochemistry sections found that TJs on jejunum epithelium completely disappeared in insulin:CMCS/CS-NPs(-) group, partially existed in insulin:CMCS/CS-NPs(+) group and appeared no change in control. Surface charges of CMCS/CS-NPs triggered intestinal epithelial TJs opening through different mechanisms. Although a down-regulation of TJs protein claudin-4 was detected in both nanoparticles groups, for phosphorylated claudin-4, the activating form, whose down-regulation occurred only in insulin:CMCS/CS-NPs(-) group. Counting upon synergetic effects of Ca2+ deprivation from adherens junctions and claudin-4 dephosphorylation and degradation, CMCS/CS-NPs(-) triggered more extensive disintegration of TJs and stronger paracellular permeability than the positive.

Abstract
Diabetic cases have increased rapidly in recent years throughout the world. Currently, for type-1 diabetes mellitus (T1DM), multiple daily insulin (MDI) injections is the most popular treatment throughout the world. At this juncture, researchers are trying to develop different insulin delivery systems, especially through oral and pulmonary route using nanocarrier based delivery system. This next generation efficient therapy for T1DM may help to improve the quality of life of diabetic patients who routinely employ insulin by the subcutaneous route. In this paper, we have depicted various next generation nanocarrier based insulin delivery systems such as chitosan-insulin nanoparticles, PLGA-insulin nanoparticles, dextran-insulin nanoparticles, polyalkylcyanoacrylated-insulin nanoparticles and solid lipid-insulin nanoparticles. Modulation of these insulin nanocarriers may lead to successful oral or pulmonary insulin nanoformulations in future clinical settings. Therefore, applications and limitations of these nanoparticles in delivering insulin to the targeted site have been thoroughly discussed.

Abstract
Polyelectrolyte complex (beads) based on N,N,N-trimethyl chitosan/alginate was successful obtained and silver nanoparticles (AgNPs) were loaded within beads. In vitro cytotoxicity assays using beads/silver nanoparticles (beads/AgNPs) provided results, indicating that this material significantly inhibited the growth of colon cancer cells (Caco-2). In vitro release studies showed that the beads stabilized AgNPs and repressed Ag(0) oxidation under gastric conditions (pH 2.0). On the other hand, at physiological condition (pH 7.4) the beads/AgNPs released 3.3 μg of Ag(+) per each beads milligram. These studies showed that the concentration of Ag(+) released (3.3 μg) was cytotoxic for the Caco-2 cells and was not cytotoxic on healthy VERO cells. This result opens new perspectives for the manufacture of biomaterials based on beads/AgNPs with anti-tumor properties.

Abstract
A series of thiol-terminated polyethylene glycol (PEG)-paclitaxel (PTX) derivatives are designed and synthesized to fabricate PTX-conjugated gold nanoparticles (PTX@GNPs) and improve their overall performance. By extending the molecular weight of PEG from 400 to 1000 Da, the optimized water solubility of the conjugate reaches 184 mg/mL, equal to 4.6 × 10(5) times that of PTX alone (0.4 μg/mL). High drug loading is obtained by eliminating the steric hindrance between PTX molecules on the surface of GNPs. The gold conjugate shows double simultaneous stimulation-induced drug release behavior in the presence of both esterase and high concentrations of glutathione. The synergic release characteristics of this conjugate results in significant performance improvements, including prolonged circulation due to high stability in vivo, targeted release of PTX inside tumor cells, and increased tumor cell killing efficiency. Improving the in vitro properties of the conjugate not only significantly enhances its therapeutic efficacy in a murine liver cancer model, but also allows drug-conjugated gold nanoparticles to be used as a promising nanoprodrug system in the cancer therapeutics.

Abstract
Recently, increasing attention has been paid to water-soluble derivatives of chitosan at its applications. The chemical characteristics and the antimicrobial properties of these salts can play significant role in pharmacological and food areas mainly as carriers for drug delivery systems and as antimicrobial packaging materials. In the current paper, a historical sequence of the main preparative methods, physical chemistry aspects, and antimicrobial activity of chitosan quaternized derivatives are presented and briefly discussed. In general, the results indicated that the quaternary derivatives had better inhibitory effects than the unmodified chitosan.

Abstract
Chitosan-Fe(0) nanoparticles (chitosan-Fe(0)) were prepared using nontoxic and biodegradable chitosan as a stabilizer. Batch experiments were conducted to evaluate the influences of initial Cr(VI) concentration and other factors on Cr(VI) reduction on the surface of the chitosan-Fe(0). The overall disappearance of Cr(VI) may include both physical adsorption of Cr(VI) onto the chitosan-Fe(0) surface and subsequent reduction of Cr(VI) to Cr(III). The rate of reduction of Cr(VI) to Cr(III) can be expressed by a pseudo-first-order reaction kinetics. The rate constants increase with the increase in temperature and iron loading but decrease with the increase in initial Cr(VI) concentration and pH. The apparent activation energy is found to be 33 kJ mol(-1), which is characteristic of a chemically controlled reaction. Characterization with high-resolution X-ray photoelectron spectroscopy reveals that after the reaction, relative to Cr(VI) and Fe(0), Cr(III) and Fe(III) are the predominant species on the surface of chitosan-Fe(0). Chitosan has also been found to inhibit the formation of Fe(III)-Cr(III) precipitation due to its high efficiency in chelating the Fe(III) ions. This study demonstrates that chitosan-Fe(0) has the potential to become an effective agent for in situ subsurface environment remediation.

Abstract
Gold nanoparticles of 5 nm diameter, stabilized by 4-(dimethylamino)pyridine (DMAP), were coated with poly(sodium 4-styrene sulfonate) (PSS) via electrostatic self-assembly. The suspension stability, monitored by the gold surface plasmon band (SPB), was studied by varying the pH, the PSS chain length, and PSS concentration. Enhanced stability is obtained at pH 10 (above the pKa of DMAP) when the polymer chain length matches or exceeds the particle circumference. Solid state 13C NMR was used to determine the presence of DMAP and polymers after subsequent deposition of weak and strong polycations: poly(allylamine hydrochloride) (PAH) and poly(diallyldimethylammonium chloride) (PDADMAC). At pH 10, DMAP remains associated with the nanoparticle after the first PSS layer has been formed. When PAH or PDADMAC are subsequently added at pH 4.5, DMAP is expelled, the suspensions remain stable, and zeta potential values indicate complete charge reversal. In the case of PDADMAC, however, the first layer of PSS is not fully retained. When PDADMAC is added at pH 10, DMAP and the first PSS layer are retained but lower zeta potentials and a higher SPB shift indicate a degraded stability. For PAH addition at pH 9.5, both DMAP and PSS are expelled and the suspension becomes unstable. These differences in stability of the multilayer components and the nanoparticle suspension are rationalized in terms of chain flexibility, polymer charge density, and the ability of the polymer functional groups to directly interact with the gold surface.

Abstract
Gold particles have been used as a carrier for transdermal gene delivery, which may cause adverse side effects when accumulated. In this study, biodegradable nanoparticles, composed of chitosan (CS) and poly-gamma-glutamic acid (gamma-PGA), were prepared by an ionic-gelation method for transdermal DNA delivery (CS/gamma-PGA/DNA) using a low-pressure gene gun. The conventional CS/DNA without the incorporation of gamma-PGA was used as a control. Small-angle X-ray scattering (SAXS) was used to examine the internal structures of test nanoparticles, while identification of their constituents was conducted by Fourier transformed infrared (FT-IR) spectroscopy. The CS/gamma-PGA/DNA were spherical in shape with a relatively homogeneous size distribution. In contrast, CS/DNA had a heterogeneous size distribution with a donut, rod or pretzel shape. Both test nanoparticles were able to effectively retain the encapsulated DNA and protect it from nuclease degradation. As compared with CS/DNA, CS/gamma-PGA/DNA improved their penetration depth into the mouse skin and enhanced gene expression. These observations may be attributed to the fact that CS/gamma-PGA/DNA were more compact in their internal structures and had a greater density than their CS/DNA counterparts, thus having a larger momentum to penetrate into the skin barrier. The results revealed that CS/gamma-PGA/DNA may substitute gold particles as a DNA carrier for transdermal gene delivery.

Abstract
Herein, we have successfully introduced the stimuli-response concept into the controllable synthesis of gold nanoparticles (AuNPs) with designed properties. We used a pH-responsive zwitterionic polymer that acted as a template and a stabilizer. Gold colloids prepared in situ from the polymer solution have a narrow size distribution of about 5 nm. The assembly and disassembly of AuNPs can be finely tuned by modulating the net charges of the zwitterionic polymer so that they are either positive or negative as a function of the solution pH. Different aggregates and colors appear on altering the solution pH. In acidic solutions, gold colloids form large symmetrical aggregates, while the AuNPs disperse in solutions with a pH approximately 9.6. However, as the solution pH increases (>9.6), needle-like aggregates with a small interparticle distances are formed. On the basis of TEM, SEM, 1H NMR and UV/Vis measurements, we attribute pH-triggered aggregation and color changes of the gold colloids to the ionization process and conformational change of the polymer. The ionization process governs the choice of ligand anchored on the surface of AuNPs, and the conformational change of the polymer modulates the interspaces between AuNPs. The present approach, which is based on a rational design of the physicochemical properties of the template used in the synthesis process, provides a powerful means to control the properties of the nanomaterial. Furthermore, the colorimetric readout can be visualized and applied to future studies on nanoscale switches and sensors.
